In the same flask as in Example 1 were charged 2 g of benzaldehyde, 50 g of dioxane as the reaction medium and 2 g of a catalyst in which 5 percent by weight of palladium metal together with thallium nitrate with an atomic ratio of Pd to Tl being 1 to 0.1. The reaction was conducted at a reaction temperature of 40° C. by introducing ammonia gas at a rate of 1 l/hour and oxygen at a rate of 10 l/hour at the same time into the flask for 2 hours to give benzamide at a yield of 71%.

1. customwas conducted at a reaction temperature of 40° C.
